LD error after gcc upgrade on Alpha XP1000

[Lupin_the_3rd]

Hello all, I've just emerged the latest stable gcc on my alpha. I followed the steps as in the Gentoo gcc upgrade guide:

# emerge -u gcc
# env-update && source /etc/profile
# emerge --oneshot libtool

It appears to be working:

elysium linux # gcc-config -l
[1] alpha-unknown-linux-gnu-4.6.3 *

elysium linux # gcc --version
gcc (Gentoo 4.6.3 p1.9, pie-0.5.2) 4.6.3

When I try to build a kernel however, I get the following errors:

Has anyone else experienced such a thing? And advise to resolve this?

Thank you

I found an answer here:

http://en.usenet.digipedia.org/thread/19006/1777/

"The relocation truncated to fit: GPREL16 against ... error is caused by the kernel being too large and compiling with -msmall-data. We've really got to do something about this -- this happens way too often to way too many people."

It's strange though, since I build this exact same kernel, exact same .config file and it built just fine without error before upgrading gcc. Weird.

Well, it seems I still need a solution. I've stripped just about everything I can out of the kernel. No more sound, etc. All that's left is the bare basics to make a running system, and still the compile fails with the same error...

Found a workaround here: http://debian.2.n7.nabble.com/gcc-4-6-msmall-data-td2133643.html

"You can change -msmall-data to -mlarge-data in arch/alpha/Makefile."

I don't know what the implications of doing this are, or why it's needed, but it made my kernel compile successfully. So at a minimum, it's a viable workaround....

I have had this happen a bunch of times when building kernels for my AS1200 as well. I also needed to use the -mlarge-data setting and didn't have issues with it, but I've also noticed that it only happens with certain kernel versions. I don't always need it, and from time to time certain kernels won't recognize my scsi controller either.
